Il pre Seer



definition:
Seer - 'one who sees the future' First in the audio chain after the source the Seer 'sees'  all that will be heard and conveys its musical truth.  The Seer offers the enthusiast a high standard compact and  versatile all tube preamplifier.

Seer Line
- with five inputs, as a line-level only model  The line stage is designed using similar circuitry techniques  employed by its two box counterpart the Prophet preamplifier,  but utilizing a different tube and a less exotic power supply.  Each line channel utilizes a low noise double triode operated  in single ended class A. With a minimum of coupling components  between stages the circuit achieves a very wide bandwidth of  5 Hz to  115kHz, providing admirable results with high quality  CD players.
 

The non-buffered output is suitable for driving medium lengths  of inter-connects giving meritorious results in systems where  the Seer would be the sole tube amplifier component, conveying  a natural musical tonal balance to ones system, especially  popular used with solid-state power amplifiers.

All inputs are hard wired for maximum signal transfer and  high quality gold plated RCA phono sockets are mounted on  a non-magnetic back-panel for minimum interference.  All circuitry is mounted on a double sided 3/32 fibreglass pcb  with 3oz copper tracks and combining elegant circuit layout  and high quality components such as gold plated tube bases  1% tolerance metal film resistors and polypropylene capacitors,
the Seer presents music with excellent clarity unusual for  tube preamplifiers in this price range.

The power supply incorporates a high quality potted toroidal  power transformer together with a solid state regulated heater  supply and hum filtered high tension supply. This low noise  supply allows the Seer to work at maximum gain with an  absence of background noise especially useful when listening
to the phono input.  All the electronics are housed in a fully screened chassis and  to compliment its elegant lines the front panel is machined  from solid 6mm aluminium billet with a brushed anodised finish.
 

Il finale Unisis

 

The Unisis was developed in 1990 by Tube Technology  and even after fifteen years it is still a much sought  after amplifier, combining the classic virtues of tube  amplifier design with the modern 'clean' power delivery often only found in higher power designs.  It has often been imitated by other manufacturers  but never equalled.

The Unisis Signature is a vast improvement over its famous  predecessor. It features a new high current driver stage,  uprated power supply and best of all a superb new output  transformer which has been in development over the last  two years.   Other major improvements are individual output tube  protection and outboard bias meter acceptability,  allowing easier maintenance of the output tubes.

All of these improvements add up to a formidable amplifying  system, with improved bass performance and amazing control  and presence for an amplifier of this power rating, we  believe you will be delighted with the speed, delicacy  and openness of this exceptionally beautiful power-house.

Power is delivered into the most difficult of loads including  electrostatic speakers, which make most solid-state designs  curl up their toes. This neat package will take pride of place  in your listening room and become the centre of the most  ambitious of hi-fi systems where high power output is not  of paramount importance.  The chassis is hand-crafted from sixteen gauge non-magnetic  high purity stainless steel.

All signal paths are hard wired with PCOCC and silver cables  and kept to a minimum length. Inputs for are through high  quality gold plated RCA phono sockets and outputs through  a high quality pair of gold plated 4mm binding posts for  each channel.  The power amplifier section employs the EL84 output tube,  the smaller brother of the EL34 as used in the Genetix and  Synergy. This tube has a very fluid and crisp sound which  injects exciting realism into a music performance.

The new and improved output transformers are designed to our proprietary design and each transformer is painstakingly  hand wound to our exacting specifications. The output  transformer is the most important component in a tube  amplifier and our obsession for getting this right is even  relayed in the manufacturing process, where during winding inductance measurements are taken for extra precision  and consistency.

The power and preamplifier printed circuit boards are through  plated 3/32 fibreglass, three ounce copper fitted with silver  contact ceramic tube bases and component quality is carefully  selected for both musicality and reliability, including 1% metal  metal film resistors, polypropylene capacitors and long life  low impedance custom power supply capacitors.  The Unisis Power may be switched from a Stereo 35 Watt
amplifier to a mono 70 watt amplifier, so is very useful  for either bi-ampling or mono-blocking if higher power  requirements are needed for more hungry loudspeakers.

Come suonano :

 

Accoppiata davvero eccellente , piacevolissima , sopratutto per chi ama  questa valvola che risulta sempre  dolce e  leggermente frizzante.  I 35 watt sono pi¨ che sufficienti per pilotare la maggior parte dei diffusori commerciali con ottimi risultati.
